These came out of my truck,ring and pinion were Precision gears. The spider gear is from the eaton. I haven't even been on slicks this year. Oh well, new parts are on the way. Pics added.

 

did this happen on a hard launch or something?

 

I think it broke when I was pulling out of a parking lot, crossing over those wide yellow stripes and nailed it. That was the last time i got into it before it started making the logging truck noise. New eaton posi and gears came today, I'll be rollin soon .

 

Do you happen to know what material they are made of? 4340 Steel? Just curious.

 

Get the new rear end parts Cryo'd

 

what is cryo'd and who does it? I don't know what kind of metal they are made of.

 

heres a place that does it

Pretty neat stuff indeed lots of nascar teams do it

 

I was about to be worried that my eaton posi I have wont be strong enough after all, but then I saw "511rwhp 491tq, 12.47 @111" in your sig I wont be making nearly that much power even after the blower.....I'm thinking about 390 rwhp

 

I did a little research and I think the material is 8620 Forged Steel which is good stuff. You just have a lot of torque at the rear wheels.
